:BFECIFICATION forming part of Letters Patent No. 306,309, dated October 7, 1884.

Application tiled January 524, 1884. (No model.)

To all whom t may concern:

Be it known that I, THOMAS C. YOUNG, a citizen ofthe United States of America, residing at St. Charles, in the county of Madison and State of Iowa, have invented certain new and useful Improvements in Corn-Planters; and I do herebydeclare the following to be a full, clear, and exact description of the inven tion, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, .which .form Va part of this specification.

My invention relates 4to certain improvements in corn-planters; and it consists of the improved construction and combinations of parts, fully described hereinafter, whereby machines of the class to which my invention appertains are greatly improved, the planting operations rendered positive and certain, and the general structure made more durable and simple.

In the accompanying drawings, Figure l is a plan view ofa planter constructed in accordance with my invention. Fig. 2 is a section on the line l 2 of Fig. l. Fig. 3 is a front view ofthe drum, and Fi l is a detail view of one ofthe journal-boxes adjusted to the inner sides ofthe frame, and in which one of the journals of the revolving drum bears. Fig. is an* other detail.

The general construction of the machine in which the present improvements are embodied is somewhat similar to that shown and described in the Letters Patent No. 185,615, granted to me December 19, 1876, to which special reference may be had in order to comprehend such general construction. In said patented construction a pair of sleeves sliding on the shaft of a revolving drum carried each a small arm adapted, when the sleeves were moved, to gear with a iixed part of the shaft, which reciproeatcd the slide and the cutoff oi' each of the hopper andthe delivery-tubes. In the present improvement the carrying-wheels are located on a pivoted frame independent of the revolving drum I3. The journals a of the drum B bear in boxes b, secured each to a plate, C, having vertical slots c, through which the heads of the secnringbolts located in the frame pass, and are threaded to receive nuts adapted to clamp the plate C against the'side of the frame to vertically adj ust the boxes and the drum. The drum B carries near each end a circular saw or toothed wheel, l), provided on its inner and outer sides, and diametrieally opposite each, other, with plates d d', the outer plate, d, provided with curved slots e, in which arelocated horizontal pins f, secured to the plate d, and threaded on the ends bearing in the slots, so as to be clamped at any point along the said slots by means of nuts g. Bars E are arranged between the saws D parallel with the shaft i1, of the drum, and are recessed at their ends to embrace one of the spokes, fi, of the circular saws, to prevent lateral displacement ofthe said bars, arched springs I, secured to the shaft h of the drum B, affording bearings for the bars E. 'Iwo small rock-shafts, F F, are journaled in bearings j on the side bars of the fraaie, and carry arms 7D' k', connected, respectively, to the slide d2 of each seedhopper G, and to the cut-off located at the lower end or' each grain-spout II. The inner end of each rock-shaft F projects sufficiently within the supportingframe as to be on a line with the saws located on the drum B, and each rock-shaft carries at said inner end a bracket, m, having pivoted thereto an arm, a, adapted to be moved to a vertical or horizontal position. A leaf-spring, q, secured, respectively, to the planter below the seed-hopper and to each rock-shaft', effects the return of the seedslide to its normal position after said shaft is turned in its bearings. A cut-oil",l s, is secured `to the upper face of each seed-slide Z, and is provided with a slot, t, to adjust the degree to which the other end, s, of the same covers the opening in said slide, and thus regulates the quantity of seed passing into the deliverytube. The said end s is also bent to bear against the under side of the bottom of the seed-hopper, and effects the positive movement ofthe slide within the opening.

From the foregoing description it will be apparent that the arrangement of bearingboxcs for the drum permits the vertical adjustment of the same, thus regulating the depth of the channels made by the circular saws; that the marking-bars E, by being spring-seated, do not communicate to the drum any shock IOO ihey receive by meeting` with an obstruction and interfering with the even cut oi' the said saws, and that as the said saws revolve the horizontal pins on the same strike the vertical arms n, rocking the shafts F in their bearings and operating the seed-slides and cut-oils. Moreover, it will be obvious that the horizontal pins j" of each saw can be so adjusted in the curved slots of the plates d d as to vary the interval of time between the successive contactof each pin with the vertical arm oi the rock-shaft, and hence vary the dropping of the grain.

By moving the cani-button of either roclshaft, the same, with its seed-slide and cut-oil` connections, may be suspended independently of the dropping devices of the other side of the machine, or the operation of both may be dis continued, .if desired.

I claiml. The combination, in a corn-planter, of a .revolving drum provided with circular side sections and with spring-seated marking-bars, and bearing in vertically-adjustable bearingboXes, substantially as set forth.

2. The combination, in a corn-planter, of a revolving drum provided with circular side sections having slotted plates bolted to their-` sides and horizontal pins adjustably clamped in said slots, and adapted to contact with and operate the seed-slides and cutoffs upon the revolution of the drum, substantially as set forth.

3. The combination, in a corn-planter, of a drum having` circular side sections provided with plates having curved slots, of horizontal pins clamped adjustably in said slots, and adapted when the drum is rotated to come in contact with an arm pivoted in a bracket secured to the ends oi" a rook-shaft operating the seed-slides and cutoffs7 and adapted to be retained 'in a vertical position by cam-buttons, substantially as set forth.

In testimony whereofI ai'iiX my signature in presence of two witnesses.
